I am trying to do something I thought would be simple in javascript, and I'm at a loss. First code is GOOD code, except that it does not account for the possibility that the button(s) in question do NOT exist. The second and third subsets are two of several attempts to do just that. Code:
View 2 RepliesI have 10 buttons on a page, and 10 more "onmouseover buttons" that correlate to the first set. Each button or onmouseover button is only 1-2KB! But I can still hold the mouse over a button for a couple seconds until it loads the onmouseover button. I'm using javascript to have the buttons change. The page does load a 2MB video. Could that be the cause? Can I tell it to load the buttons first somehow?

what i need to do to add all the radio botton and check box. i already finish the add formula on the checkbox but i do not know how to add the two selected radio buttons to my checkbox buttons.for example:
O selected is 80
O 60
O 60
O selected is 15
O 15
O 25[code].....
What happens is the user selects the number of buttons depending on the number entered in the text box. If the number is 3 in the text box, then the user can only select 3 buttons, if more buttons are selected then it comes with an alert message saying user is beyond limit deselect a button to be able to choose another button.
But these are the problems I have encounted: If I type in "2" in the textbox for example, it allows me to select 2 buttons and comes up with alert if more buttons clicked.
problem 1: but if I change the figure in text box from "2" to "5", then it only allows me to select 3 buttons (I think it is adding 2 from the previous value and 3 to make the current value 5)
problem 2: If I enter a value less than current value, so in this example if I enter in 1 in the textbox which is obviously less than 2, then it lets the user select unlimited number of buttons.
So does anyone know how to fix these problems so that the amount of buttons selected matches correctly to the value in the textbox?
I want my radio buttons to become submit buttons as well. So when a user clicks on a radio button it submits the action and refreshes the page accordingly. As of now using only using onclick="this.form.submit()" the page only refreshes with no change. Here is a copy of the entire form. It is a custom shipping options form (I did not create it).
<!-- Custom shipping form -->
<form action="" method="post" name="update_shipping">
<table width="300">
<tr>
<td><label>
<input <?php if (!(strcmp($_SESSION['shippingmethod'],"1"))) {echo "checked="checked"";} ?>

I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
I'm trying to create a questionnaire style series of radio buttons which are hidden and then a different set of radio buttons displayed depending on the previous answer. eg
Q1 Is it a man? (if select yes then display)
Q2 Is he called John? (if no then display)
Q3 Is he called Gary? and so on...
I've been testing using the code below but wondered if anyone had any ideas on how this could be done easily?
I'm trying to get a radio button validation for different sets of radio buttons that simply contains Yes & No buttons.
Here's what I'm trying to do:
Question 1: if Yes, then (Alert 1) if No, then (Alert 2) (if Yes, then Question 2 appears) *Up to here I'm happy- can't figure out the rest*
Question 2: if Yes, then (Alert 1) if No, then (Alert 2) (if Yes, then Question 3 appears)
I need the Alerts to be swapped from this point*
Question 3: if Yes, then (Alert 2) if No, then (Alert 1) (if NO, then Question 4 appears)
Identical for Question 5, and for Last Question 6 Alerts swapped back again.)
Here's the script that I managed to piece together:
I'm trying to use JS to move the cursor from my user login text field
to the password text field - I've put the onKeyPress() event in the
user input tag but then I press the Tab key the cursor doesn't move -
function detect_tab_key()
{
var key_code = window.event.keyCode;
if (key_code == 9)
{
document.forms[0].frm_password.focus();
document.forms[0].frm_password.select();
}
}
I would to change the color of some td cells if there is text in it. Right now this code does the job, but it changes the color of evry table. I'd like to know a way to do this on one table in my page and not all of them.
var count='0';
var TDs=document.getElementsByTagName('td')
var length=TDs.length;
i='0';
[Code]....
example: onkeypress="return eventHandlerFunction(event)"
Why is it that you need the return keyword?
Where does the argument event come from?
I know it works, I just want to know why it works.
I've been looking at some refferences and can't seem to find an answer if someone could give me an explanation or point me to a website, that would be great.
Is there any way javascript can know when a swf is clicked on?

I have a dynamic web page with three vertical divs.
In the style attribute, I do not specify the div height because I don't know that until they're draw by the browser.
However, I'd like to add a fouth horizontal div acfross the bottom of the page at the bottom of the tallest of the vertical divs.
Is there any way to get the height of a div after it's drawn?
If I detect an empty textbox, I fill it with a value ('Dad'). If I do this twice, the second time around IE 6 fails to notice that I've cleared the textbox again, thus leaving the textbox cleared. Is there a recommended workaround? Opera 7.23 is detecting the second deletion fine.

I am trying to detect whether a user entered text in a textarea
or hit the delete/backspace button (thus, erasing something). Once
that is detected, I would like to set "var bSaveRequired = true;". It
would be great if this function worked cross-browser -- IE 6.0 and
Firefox.
Say I'm on the site www.xyz.com and on a certain page if the user leaves the domain xyz.com, I have a popup cme up w/ stuff. I don't need to know what the new domain is, I just want to know if the user left / is leaving xyz.com.
View 1 Replies View RelatedI'm trying to determine if the user clicks the
stop button during a post send, basically. Specifically, if a user is
uploading a file to my server, and they click stop at some point, I
need to be able to tell the server that stop was clicked, so it doesn't
think that's the whole file. I've noticed that an error message is
written to the Apache log, but that seems like a strange way to keep
track of user-interrupted events. (Note: this is Apache/mod_perl
server-side)
I guess what I'm thinking now is that JavaScript detects the stop
(since it is client-side), then sends a message to the server that an
error occurred, or something. Like I said, the onstop event is not
doing what I'm expecting, and Firefox doesn't like it anyway, not to
metion the other browsers out there. So my question is what's the
"idiom" or "standard way" of detecting this sort of situation. I'm
quite certain I'm not the first one to need it.
If I want to detect a user's language, so that I can
change some text to suit them, how do I do that in
Javascript?
Or aren't modern browsers supposed to be able
to cope with more than one language on a page,
separated somehow by language identifiers,
and display only the appropriate text? Maybe
I was dreaming when I read that.
I'd like to be able to detect when page content is dynamically changed
by Javascript. I'd like to detect any changes to the content, such as
the addition of new DOM elements and when DOM elements that are hidden
are made visible (or vice versa). I will have no advance knowledge of
the scripts that will be run along with the script I will create.
I've implemented a solution that works reasonably well, but I'm not
sure if there are cases I'm not thinking of where it will fail, or if
there are more efficient means of doing the same thing.
My solution is to simply retrieve and periodically compare the content
of the innerHTML property of the main body tag elemnt.
So, summarized as follows:
function check() {
var bodyContent = document.getElementsByTagName('body')[0];
if(bodyContent != oldBodyContent) {
alert('body changed');
}
setTimeout(check, 500);
}
Is there a better way? What won't this catch?
I am writing a script that uses xmlhttp.open, when i attempt to open a protected page I get the login prompt for my htpasswd. Is it possible to detect if there is a login requirement before the login prompt and if there is a login just do something else? I can use xmlhttp.status and check for 200 but if I do this then it would happen after the login prompt.
View 1 Replies View RelatedI'm making an Intranet site for someone who is not very familiar wit
making websites, thus I would like to make it as simple as possible fo
her when she needs to update it.
The intranet site uses frames - one menu frame that is always present
and one frame into which the content is loaded. The intranet sit
features many, many links to both internal and external pages - i
internal pages within the intranet and external pages on the interne
(http://)
What I would like to do is make it so that if a link is internal, th
content will load into the content frame and the menu frame will remai
at the side, but if the link is external, it will load the target int
the entire browser window. Using HTML, this would simply be a matter o
stating the href and then target="content_frame" for internal pages o
target="_top" for external pages.
But, like I said, I am making this site for someone who is not familia
with linking targets and even if I told her to define the targe
whenever she makes a link, she'd probably forget or get confused an
then wonder why external pages are loading with the intranet menu fram
still present or why intranet pages are loading with no menu at th
side!
While I have good experience with HTML, I am fairly new to JavaScript
which is why I am here asking for help.
I understand that Javascript can detect the protocol of a link,
believe you would use "link.protocol". In basic terms, what I woul
like to do is:
if link.protocol = "http://" then target="_top" els
target="content_frame"
But since I'm not familiar with the precise way of coding JavaScript,
would just like some help with transforming this into correc
JavaScript code so that it will work.
